Abstract
Description
technical field
[0001] The invention relates to the technical field of traffic control, in particular to a traffic control system utilizing three-coordinate radar detection and optimization. Background technique
[0002] After decades of development, road traffic control has formed a relatively complete theoretical system in two ways: multi-period fixed-period control and induction signal control. The multi-period and fixed-period control method is to divide a day into multiple time periods based on historical traffic flow data, and each time period is equipped with different cycle lengths and green signal ratios according to the changing trend of traffic flow. Induction signal control is based on the point or interface real-time traffic data provided by the upstream detector of the intersection entrance, and determines whether the current green light release signal is extended or terminated according to the gap time between vehicles arriving at the intersection. In recent ...
